What we build
CommercialSolarGuy builds every major type of commercial solar installation across the Northeast:
- Rooftop solar — Ballasted and attached systems on flat and pitched commercial roofs. Featured projects include a rooftop installation at Harvard University and multi-building rooftop systems in Boston and Rhode Island.
- Ground-mount solar — Pile-driven and ballasted ground arrays on open land, from small installations to multi-megawatt solar farms. Featured project: ground-mounted solar farm in Rhode Island.
- Solar carports — Engineered canopy structures over parking lots that generate power while providing shaded parking, with optional EV charging integration.
- Agrivoltaic solar — Dual-use installations combining active farming with solar generation, qualifying for the Massachusetts SMART dual-use adder.
- Solar-plus-storage — Hybrid systems pairing solar with battery energy storage to manage demand charges, maximize interconnection capacity, and provide resilience.
Our team has installed dozens of megawatts of commercial solar across rooftops, parking lots, and land in New England

What makes commercial solar unique?
Getting a commercial solar installation is not as simple as putting some panels on the roof and turning them on—it’s a significant financial investment designed to provide long-term value to your business. In order to do that, every project requires guidance from knowledgeable experts.
Here are some key factors that set commercial solar projects apart:
- Diverse Goals: Businesses and landowners use solar to achieve multiple goals, including energy savings, meeting organizational sustainability (ESG) targets, and hedging against demand charges and future changes in energy price stability.
- Complex finances: The proper financial structure is essential to a good commercial solar project. Each project involves a mix of federal and state incentives, accelerated depreciation schedules (MACRS), specialized financing options, and the potential for creating new revenue streams from selling energy credits. The ideal outcome is working with these factors to create a calculated, long-term ROI for your business.
- Precise engineering requirements: Whether you’re looking for a solar installation on a commercial rooftop or a ground-mounted system on land you own, the process of engineering the system is complex, requiring detailed site surveys and structural analysis, careful calculations, and expert knowledge of building and land-use codes.
